How to use the online alarm clock
While getting ready for the lunchtime concert at the cathedral, set the alarm for 2:27 pm before packing your bag or checking the route. That gives you a clear cue to stop what you are doing and leave at the time you planned, rather than noticing the clock as 3:00 pm approaches. Allow a little extra time for walking through the city centre and finding the correct cathedral entrance.
Your cathedral concert reminder depends on this browser page remaining open and the phone or computer staying awake; closing the page, quitting the browser or letting the machine sleep means no alarm will sound. Leave the page visible while you finish preparing, keep the volume high enough to hear, and avoid switching to silent mode. If the concert timing matters closely, a separate phone alarm provides a useful backup.
Heading towards a cathedral at 2:27 pm can mean moving between warm streets and heavily air-conditioned indoor spaces. Carry a light layer that is easy to put on once seated, especially if the nave feels cool after the midday heat outside. A small bottle of water is practical for the journey, while checking the cathedral’s entry arrangements beforehand can prevent an unnecessary wait outdoors.
Common questions
Can I change the sound?
Yes, there is a short list of tones to pick from before you press Start. Softer sounds are easy to sleep through, so a firmer bell tends to be the safer choice for anything early in the morning.
Will it still be right when the clocks change?
Yes. It reads your device's local clock, so the move between GMT and BST at the end of March and October is picked up automatically, as long as the computer's date, time and time zone are set correctly.
Can I use this on a phone?
It works in a mobile browser, but phones lock the screen and suspend background tabs far more readily than a laptop does, which can stop the alarm sounding. For anything important, a desktop or a plugged-in laptop is the steadier option.
Does the alarm still work if I close the tab?
No. Everything runs inside this page, so closing the tab — or quitting the browser altogether — ends the countdown there and then. Leaving it open in the background is all it asks, and switching to another tab makes no difference.
